Description of government structure:

Assembly: Lithuania has a unicameral Parliament (Seimas) with 141 seats.

Description of electoral system:

The President is elected by plurality vote to serve a 5-year term.

The Prime Minister is appointed by the president with the approval of the parliament.

In the Parliament (Seimas), 71 members are elected by absolute majority vote in single-member constituencies to serve 4-year terms and 70 members are elected through an open-list proportional representation system to serve 4-year terms.[1]

[1] In the nominal tier, if at least 40 percent of registered voters vote in the election, candidates must have an absolute majority of votes to win. If fewer than 40 percent of those registered vote, a candidate needs only at least 20 percent of votes to win. If there are multiple candidates and none reach the required threshold, there is a runoff round between the two candidates with the most votes. In the proportional tier, an election is valid if at least 25 percent of registered voters turn out.
